rinse it with a low flow of plain tap water.
HTC Butterfly 3 must not be exposed to non-fresh water, high water pressure, or sand since these
may cause overheating, electric shock, or damage to the phone. For usage precautions and tips on
care and maintenance, see Important: Do's and don'ts on page 28 and Care and maintenance tips
on page 29. Also make sure to read the Safety guide that comes with your phone.
Important: Do's and don'ts
Before use
Make sure the nano SIM and microSD trays are inserted into the slots securely and their covers are
closed tightly. For instructions, see Inserting a nano SIM card on page 12 and Inserting the microSD
card on page 14.
§ Never attempt to insert or remove the nano SIM and microSD trays with gloves, wet hands,
or when the phone is wet.
§ Before closing the covers, wipe off every drop of water or dirt with a clean, dry cloth.
§ When closing the covers, make sure that no hairs, fibers, or small particles are caught
between the covers and the slot openings to prevent water from seeping through the gaps and
entering the phone.
While using
Don't immerse HTC Butterfly 3 in or let the USB port and headset jack come in contact with the
following:
29 Your first week with your new phone
§ Water containing soap, detergent, or shower gel
§ Sea water, swimming pools, spas, and hot springs
§ Any liquid besides tap water such as alcohol, juices, and condiments
Don't operate HTC Butterfly 3 underwater.
While the phone is immersed in water, don't press the POWER and VOLUME buttons.
Under moderate rain, you can make or receive calls with wet hands and without an umbrella. To be
specific, the rainfall's precipitation rate must be within 20 mm/hour.
You can make or receive calls while holding the phone with wet hands, such as when you're in the
bathroom or kitchen. Be reminded about the following:
§ Don't hold the phone directly under the shower spray since it is not designed to withstand
high water pressure.
§ Don't immerse the phone in a hot tub.
§ Avoid leaving the phone in humid places such as the bathroom or kitchen for too long since it
is not moisture-proof.
Keep the phone away from sand. Sound volume may decrease if sand gets into the
earpiece, microphone, or speakers. If sand gets inside the phone, this may cause
overheating or a fault.
Don't plug in your headset when the headset jack has been exposed to water, dust, or other particles.
Don't charge the battery while the phone is wet. Also, the power adapter and accessories are not
water resistant. Never use them in wet areas such as in the bathroom or kitchen since contact with
water may cause malfunction, electric shock, or other hazards.
Care and maintenance tips
Cleaning
If the USB port and headset jack have had contact with salt water, liquid chemicals, dust, or other
contaminants, immediately rinse using fresh water. These contaminants may damage the connector
pins.
§ Before rinsing, make sure the nano SIM and microSD covers are properly closed. See
Inserting a nano SIM card on page 12 and Inserting the microSD card on page 14.
§ While rinsing, don't press on the covers to avoid having gaps around the covers which may
allow water to seep through the gaps.
§ Hold the phone at a distance of about 10 cm under a faucet or showerhead and rinse using a
low flow of water. To be specific, the water flow must be less than 6 liter/minute at a room
temperature of 5°C to 35°C.
§ Rinse the phone by hand only. Don't use a brush or sponge.
30 Your first week with your new phone
From time to time, clean the USB port and headset jack with dry cotton swabs to avoid having soiled
connectors which may affect the cable connection. Wipe gently with care to prevent deforming the
connectors.
Drying
After HTC Butterfly 3 gets wet, drain the water off the phone to avoid getting your clothes or bag
wet. Also, the sound volume of the earpiece, speakers, and microphone may be less audible if these
parts are not dried well.
1. Wipe off the water from the phone with a clean, dry cloth.
2. The display may not respond accurately to touch gestures when it's wet. For the touch screen
and lenses, wipe with a soft dry cloth such as a microfiber cloth that will not scratch the
surface.
3. To drain water off the USB port and headset jack, hold the phone firmly and shake off the
water from each port.
4. Also make sure to shake off the water if it gets into the gaps around the POWER and
VOLUME buttons or into the earpiece, speakers, or microphone. Don't use cotton swabs to
wipe the earpiece, speakers, and microphone.
5. After shaking off the water, leave the phone at room temperature for 3 hours or so to let it dry
completely.
Moisture may remain even after shaking off the water. This does not affect usage, but it's best to
keep the phone away from humid places to let the phone dry.
If condensation forms inside the display such as when there's a drastic change in temperature, place
the phone at room temperature until condensation disappears.
Other tips
§ Avoid storing the phone while it's wet. Water drops may turn to frost in cold climates.
§ Avoid leaving the phone inside your bag or pocket for a long time since moisture may
accumulate on the phone.
§ Don't use the phone near hot splashing water or near hot air such as a hair dryer.
§ Don't place the phone where it gets extremely hot or cold such as near a stove or inside a
refrigerator.
